Title: A hierarchical downlink scheduler for a processed satellite payload
Inventor: KINCAID JASON R
IPC: H04L13/08
Filed: 2000-03-14
Abstract: A downlink scheduler (20) is provided for scheduling the downlink transmission of data cells in a spot beam processing satellite (12). The downlink scheduler (20) includes a beam selector (48) for selecting one of the spot beams associated with the satellite (12), a plurality of wholesale selectors (50) for selecting one of a plurality of wholesalers, such that each of the wholesale selectors (50) is associated with one of the spot beams, and a plurality of retail selectors (52) for selecting one of a plurality of retail connections, such that each of the retail selectors (52) is associated with one of the wholesalers. Each of the selectors may use a packet fair queuing (PFQ) method to make its selection.  The downlink scheduler (20) then passes at least one data cell from a selected retail connection to a downlink modulator (24), thereby scheduling the downlink transmission of data cells in the satellite.

Title: Low power rectifier circuit
Inventor: GORD JOHN C
IPC: H02M7/12
Filed: 1998-09-11
Abstract: A low power switched rectifier circuit is realized using P-MOS and N-MOS FET  switches that are turned ON/OFF at just the right time by a detector and inverter circuit (which form an integral part of the rectifier circuit) to rectify an incoming ac signal in a highly efficient manner. Parasitic diodes and transistors that form an integral part of the FET circuitry respond to and rectify the incoming signal during start up, i.e., when no supply voltage is yet present, thereby providing sufficient operating voltage for the FET switches to begin to perform their intended rectifying function. In the absence of an incoming ac signal, i.e., during the time between biphasic pulses, the rectifier circuit is biased with an extremely small static bias current but in the presence of an incoming ac signal, at a time when the positive and negative phases of the incoming signal are to be connected to positive and negative supply lines, a much larger dynamic bias current is automatically triggered.

Title: Method for the analysis and standardization of bills of resources
Inventor: DEBUSK BRIAN C
IPC: G06Q10/06
Filed: 1998-09-24
Abstract: Disclosed is a method for the analysis and standardization of bills of resources to be used during the performance of a given procedure. Bills of resources to be analyzed are converted to models for manipulation (104). The models are manipulated according to a mathematical algorithm (106) which highlights their relative similarities and dissimilarities (108). Based upon this expression the utilization, consumption, or other characteristic of the bills of resources or the resource listed therein may be analyzed (110). In one embodiment of the invention, the expression of the manipulated models is utilized to identify groups of similar bills of resources (112) and a standard bill of resources (116) for each group of similar bills of resources is calculated. This standard bill of resources (116) is then substituted for the different bills resources in each defined group (112).

Title: Optical recording medium and disc cartridge
Inventor: AOKI YOSHITAKA
IPC: G11B7/24
Filed: 2000-06-06
Abstract: An optical recording medium is provided which has a substrate and a signal recording layer provided on the substrate and in which an information signal is recorded in the form of microscopic pits. A light beam is focused on the signal recording layer and some change of the light beam carried by a return light from the signal recording layer is detected to read the information signal recorded on the signal recording layer. The optical recording medium has a diameter of 65 mm or less and a thickness of 0.4 to 0.7 mm. An information signal recording area extends outwardly from a radial position of 12.5 mm or less from the center of the medium. The ratio in area between the information signal recording area and non-signal recording area is 3.4 or more. The storage capacity of this medium is 2 gigabytes or more. The optical recording medium has formed at the center thereof a center hole around which an annular table-abutment convexing to one side of the medium is formed. A magnetic-clamping hub is installed in the center hole and thus the medium is magnetically clamped to a rotation driving mechanism of an optical recording and/or reproducing apparatus. The compactness and high density of recording of the optical recording medium will contribute greatly to a further compact structure of a recording and/or reproducing apparatus in which the medium is to be used.

Abstract: The present invention is a shielding material that resists both nuclear radiation and high temperatures and is especially suited to encasing radioactive waster materials to immobilize them. The material is a mixture comprised of two or more organic polymers in which included fillers are crosslinked within the phenylic side chains of the polymers and copolymers. Other fillers provide radioactive shielding and may be merely included within the cross-linked matrix. The material contains a tough matrix with embedded particles of radiation shielding substances and thermoconductive materials with an overall ceramic-like or ceramometallic properties. The material is thermosetting and can present an extremely hard material -e.g., 20,000 p.s.i. shear strength. The material is comprised of a mixture of vulcanized rubber and/or rubber-like polymers, various radiation shielding inclusions, polyimide resin and phenolformaldehyde resin. After being mixed in the proper proportions the material sets up at an elevated temperature (e.g., 260 ~C). The final material has a density of between 8 and 50 pounds per cubic foot depending on the proportion and identity of the radiation resistant inclusions.

Abstract: Cette bobine d'inductance variable présente un noyau saturable comportant trois segments (42, 43, 44), un segment central (43) et deux segments extérieurs. Un enroulement de commande est enroulé sur le segment central, deux enroulements extérieurs (46, 47) étant connectés en parallèle et enroulés sur les segments extérieurs. Les inductances des enroulements des segments extérieurs varient avec le courant traversant l'enroulement de commande. Le courant traversant l'enroulement de commande modifie le niveau de saturation des segments extérieurs. Dans un mode de réalisation, l'inductance de l'enroulement de commande est sensiblement constante, lors d'un changement de courant dans l'enroulement de commande. Dans un autre mode de réalisation, les segments extérieurs sont saturés, tandis que le segment central ne l'est pas. Des portions (48, 51) du noyau reliant les trois segments sont effilées vers le bas, de la section du segment central (43) vers les sections des segments extérieurs (42, 44). L'invention concerne en outre des procédés destinés à faire varier l'inductance d'un élément à circuit inductif, en fonction d'un courant de commande.
